How to Fix a 500 Error When Opening the Import Tab in Microsoft Purview

Product: Microsoft Purview
Device & OS: not provided
Scenario: Accessing the Import tab in the Microsoft Purview compliance portal to manage data imports.
Observed behavior: A 500 error page is displayed preventing the user from viewing or utilizing the Import tab.

Before you start

Ensure you have global administrator access to the Microsoft 365 admin center before attempting to modify role assignments in Microsoft Purview.

Solution 1Recommended

Assign the Compliance Data Administrator Role

Resolve missing Purview role permissions that cause the 500 error by adding the Compliance Data Administrator role.

Microsoft Purview requires its own specific compliance portal permissions, independent of standard Exchange admin permissions. Assigning this role grants the necessary access to the Import tab.

Log in to the Portal

Navigate to Permissions

Click on 'Permissions' or 'Role groups' in the left-hand navigation menu.

Edit Role Group

Locate and edit the 'Compliance Data Administrator' role group.

Add User

Add the affected user account to this role group and save your changes.

Assign the Compliance Data Administrator Role

Propagation Time: Role assignments in Microsoft 365 can take several hours to fully propagate. Please wait up to 24 hours if the tab is still inaccessible immediately after making changes.

Solution 2

Verify Notification Settings on the Import Form

Ensure that specific form settings, such as the 'Notify Me' option, are not blocking the submission process.

Solution 3

Sign Out and Clear Browser Cache

Force the browser to fetch the newly propagated permissions by clearing cached data.
